This endpoint requires authentication. Include your Bearer token in the Authorization header.

​
Description

This is used when the file detection flow returns low source confidence (sourceCreatorEligible: true in the upload-url response) and the user opts to create a new source rather than selecting an existing one. The endpoint reuses the parsedFileData (headers, sample rows) already stored on the detection session, so no file re-upload or re-parsing is needed. Flow:
  1. POST /file/upload-url returns detectionResults.sourceCreatorEligible: true
  2. Client calls this endpoint to start the Source Creator wizard
  3. User completes the wizard (AI mapping → query generation → save)
  4. Client calls POST /file/confirm-detection/{sessionId} with sourceCreatorSessionId
  5. File proceeds to processing queue
Authorization:
  • Required role: user or higher
